1 Claim. (Cl. 'l0- 264) This invention relates generally to a locking Fig. 2 is a transverse sectional view showing one device for the doors of automobiles and the like form of connection between the key controlled and more particularly to an arrangement wherelock and the parts upon the'opposite side of the by all of the doors of a vehicle may be manually automobile and taken substantially on the line locked or unlocked simultaneously in a single 2-2 of Fig. 3; and 5 operation from a single point. Fig. 3 is an enlarged lateralA sectional view It is the main object of this invention to prothrough one of the side posts of the automobile vide a locking arrangement for the doors of a and its associated parts. motor vehicle whereby all of the doors of said Referring to the drawing more specifically by 10 vehicle will be connected to a central lock actucharacters of reference, the numeral I0 designates l0 ating mechanism and remotely controlled and generally the bOdy f an autOnlObile haVng, in operated from a single point in a single operation. the case of a four-door closed sedan, an upright Another object of this invention is to provide post I I between the two doors I2 and I3. At a a locking arrangement for the doors of a motor position adjacent the door handles and in the l5 vehicle which may be installed to existing conpost II, as shown in the drawing, a conventional l5 structions of vehicles without extensive changes fOrIn Of key C0ntr0lled 106k i4 iS provided. Said thereto and when so installed will be highly lock carries upon the inner endof its rotative eicient for carrying out the purposes for which part I5 a bevel gear I6. Partial rotation of this it is designed. gear I 6 occurs when the key (not shown) is A further object of this invention is to provide turned in the lock Ill. 20 a locking mechanism of the character described The gear I6 iS Connected JGO a Stud Il, Which for the doors of a motor vehicle, which arrangestud is mounted for rotation in the angle bar or ment will be simple in construction, assembly and bracket I8, said bracket being SuDpOrted Within operation, which will be durable in use and which the hOllOW DOSt ll and iS Xedly SeCllred lthereto at the same time be eicient in operation and aS more Clearly illustrated in Fig. 2 thereOf- The 25 practically fool-proof. stud I'l is provided on its end opposite the end with the foregoing and other objects in view carrying the bevel gear I6 with a spur gear I9, which will appear as the description proceeds, the Whereby rOlialiOn 0f the bevel gear l5 Will Simiinvention consists in certain novel features of lal'ly rOtate the Spur gear I9. The bracket I8 has construction, arrangement and combination of also mounted thereon for rotation the spur gears 30 parts hereinafter more fully described, illustrated 20 and 2l, Whleh gears are arranged One above in the accompanying drawing, and particularly and One belOW the Spur gear i9, With their aXeS pointed out in the appended claim,it being underin alignment With the aXiS 0f the gear I9. Said stood that various changes in the form, proporgears 2U and 2l beilg in COIlStal'll'f IneSh With the tion, size and minor details of the structure may gears i9, whereby rotatien 0f the gear I9 in a 35 be made without departing from the spirit or counterclock-wlse direction as viewed in Fig. 3, sacrificing any of the advantages of the invenwill impart rOtatiOn t0 the gears 20 and 2l in a tion l clock-wise direction.

For the purpose of facilitating an understand- Rigidly Secured t0 the gear 20 fOr rotation ing of my invention, I have illustrated in the therewith iS One end 0f a bolt 22, the Opposite 40 accompanying drawing a preferred embodiment end being provided with the substantially right thereof, from an inspection of which, when conangle portion 23 adapted When the gear 20 iS sidered in connection with the following descriprOtated approximately ninety degrees (90) t0 tion, my invention, its mode of construction, asengage within a recess 24 provided therefor in sembly and operation, and many of its advantages the latch 25, which latching is normally used 45 should be readily understood and appreciated. for holding the door I3 in a closed position. Referring to the drawing in which the saine Similarly the gear 2| has rigidly secured thereto characters of reference are employed to indicate one end of a bolt 26 for rotation therewith, said corresponding or similar parts throughout the bolt 26 being provided with a substantially right several gures of the drawing: angle portion 21 at its opposite end, which end is 50 Fig. lis a fragmentary side elevational view of adapted to be received in a recess 28 provided a, portion of an automobile body illustrating one therefor in the latch 29 of the door I2 when the point of application of the key controlled lock gear 2| is swung substantially ninety degrees through which the remaining lock elements are (90) from the full line position of the bolt shown actuated; in Fig. 3 to the dotted line position shown in 55 said iigure. Suitable openings 30 and 3l may be provided in the sides of the post member Il for permitting the passage of said bolts 22 and 26 respectively into engagement with their respective latches 25 and 29.

Supported in the horizontally arranged portion 32 of the bracket i8 is a shaft 33 on one end "of which is provided a bevel gear 34 which is arranged in constant mesh with the bevel gear I6 whereby rotation of the gear I6 will impart similar rotation to the gear 3|. A ilexible shaft 35 connects the shaft 33 with a similar shaft 36 supported at the opposite side of vthe car body in the horizontally arranged portion 32 of a bracket I8', said shaft 36 being provided at its free end with a bevel gear 34 which is in constant mesh with a spur gear I6', the latter being mounted on one end of a stud shaft I1' supported in the bracket I8 and having provided on its other end opposite the bevel gear IB', a spur gear i9. The spur gear I9' is arranged for constant mesh with the gears 20 and 2l', said gears having rigidly secured thereto for rotation therewith the bolts 22 and 26 respectively, which bolts are identical in shape and construction as the bolts 23 and 26, and which cooperate with the latches provided on that side of the car body in identically the same manner as illustrated in Fig. 3.

From the foregoing it will be readily apparent that the present invention offers a most simple and at the same time a positive means for simultaneously locking all of the four doors of a vehicle from a single point in a single operation. It is to be understood that in the case of vehicles having a total of two doors only, the application of my mechanism will be substantially the same with the difference that the gear 2| and its associated bolt 26 may be eliminated.v It is also to be understood that the invention is not limited to the particular type oil, connecting means between the locking mechanisms on the two sides of the car as some means other than the flexible cable may be utilized for transmitting the motion from the bevel gear 34 to the bevel gear 34. It is also apparent that the mechanism comprises only a few parts which may be readily assembled in operative condition and when so 'assembled will be simple in operation, requiring little or no attention and is so arranged that it will not readily get out of operative condition. It will also be noted that the mechanism is positive in its operation and is capable of assembly and installation in existing construction with a minimum amount of time and labor.

It isA believed that my invention, its mode of construction and assembly, and many oi its advantages should be readily understood from the foregoing without further description, and it should also be manifest that while a preferred embodiment of the invention has been shown and described for illustrative purposes, the structural details are nevertheless capable of wide variation within the purview of my invention as dened in the appended claim.

What I claim and desire to secure by Letters Patent of the United States is:

In a. device for simultaneously locking the doors of a motor vehicle provided with centrally located side posts against which the doors of the vehicle are adapted to close, a substantially L-shapedbracket secured within each of said side posts adjacent each pair of doors, a gear rotatably mounted on one of the legs of each of said L- shaped brackets, a pair of gears also secured to said bracket and being arranged for constant mesh and in substantially vertical alignment with said first-mentioned gear, a bolt secured to each of said second-mentioned gears for rotation therewith, each of said bolts being provided with a right-angle extension adapted to enter a socket in the door for engagement with a socket provided with a conventional latch normally holding said door in closed position, a bevelled gear connected with each of said first-mentioned gears for rotation therewith, a second bevelled gear in mesh with said last-mentioned bevelled gear and rotatably supported on the second leg of each of said L-shaped brackets, means connecting together the said last-mentioned bevelled gears whereby the rotation of one will impart similar and corresponding rotation to the other. and key operated mechanism for actuating said rstmentioned bevelled gears supported by said rstmentioned leg of said L-shaped brackets.
